Return the borrowed things on time, you'll be welcome next time.; It's easy to borrow again if one returns the borrowed things in time.
好借好还,再借不难。
Note that in a closed universe you could start a journey off in one direction and, if allowed enough time, ultimately return to your starting point; in an infinite universe, you would never return.
请注意,在一个封闭的宇宙你可以朝着一个方向开始旅行,如果允许足够的时间,最终将返回到出发点;而在一个无限的宇宙中,你永远不会回来。
D-A-V-I-D Well, if I've got a five-letter word like D-A-V-I-D, well, that's like five bytes and yet we only have the ability thus far in this class to return one thing at a time I can't return five bytes to you, but wait a minute, those bytes by nature of a computer are just stored in RAM.
好的,如果有5个字母的单词,如,那是5个字节,我们只能返回一个东西,而不能返回5个字节,等一下,这些字节被计算机本能地,存储在内存中。
So this line or these lines of code up here are arguably constant time steps to say if N is less than 2 in return, that it will always take maybe one step, maybe two steps, some number of fixed CPU cycles.
如果N小于2并返回,那么这些行所对应的代码,通常只需要执行一步,或者两步,具体数字与CPU周期有关。
